Temperatures may be dropping, but that doesn’t mean we have to bid farewell to our herb gardens. Cold-hardy herbs, such as chives, mint, oregano, parsley, sage and thyme, can often survive cold-winter temperatures while continuing to produce flavorful foliage, as long as they are provided with some protection or grown indoors. Even herbs like rosemary that are more cold-sensitive can survive winter using additional methods of protection. Let’s explore different ways we can prolong the herb harvest and enjoy the fresh taste of our favorite herbs throughout the cold of winter.

1. Protect herbs from the cold by placing them in a cold frame or cloche. Covering herbs helps trap the heat that rises from the soil, elevating the temperature inside by several degrees. This can extend the growing season in both fall and spring.

Cold frames are topped with glass panes that slope downward and are situated so they face south. This ensures that the most sunlight will reach the plants inside, creating an environment that is several degrees warmer than outside.

Cloches are a smaller and more portable way to protect plants from the cold. Traditional ones are bell-shaped and made from glass. They can be expensive, but you can make your own by cutting off the bottom of a 1-gallon plastic milk jug or other large plastic container. Place each one over individual herb plants and nestle the bottom inch or two of the cloche into the soil to anchor it.

2. Add a thick layer of coarse mulch over herbs. Many herbs can grow through the winter under the insulation provided from straw, shredded bark or other coarse mulch. In areas that experience moderate-winter cold, USDA Zone 6 and warmer, herbs will continue to produce some new growth despite some winter cold. Simply pull back the mulch and cut the herbs you need, then cover them back up. While they won’t produce as much new growth as they do in the warm season, you should be able to obtain a small harvest. Don’t worry if a layer of snow falls, as it will provide additional insulation for the herbs below. Once spring arrives, you can turn the mulch into the soil.

3. Pot up herbs and move them into a frost-free greenhouse or sun porch. If you’re growing herbs in the ground, you can transfer them to pots and move them to a protected spot. Select the herbs you want to keep growing over winter, such as chives, oregano, sage and thyme. Cut them back to 1 inch tall and, using a sharp shovel, divide them at their base, making sure to include the roots so each one will fit into the container. Use well-draining planting mix in the containers and plant each herb in a separate pot. They will grow back and you’ll be able to harvest their flavorful leaves until you transplant them back into the garden once spring arrives.

4. Grow herbs in front of a sunny window. Herbs can be grown from seed or cuttings and make a great addition to a sunny kitchen window that gets at least six hours of sunlight. If using artificial lighting, 14 hours is usually sufficient. The temperature should range between 60 and 70 degrees Fahrenheit, or 15.6 and 21.1 degrees Celsius, for best results. You can transplant herbs from the garden or begin from scratch by sowing seed.

The rewards of growing herbs indoors throughout the winter are great when the fresh flavor of summer is within arm’s reach. Chives, oregano, parsley and thyme are just a few of the easiest herbs to grow on a sunny windowsill. Use a well-draining planting mix in your container. Water deeply when the top inch of soil is almost completely dry.

5. Extend the life of fresh herbs by putting them in water. Herbs such as basil and mint grow quickly when placed in a container of water for a few weeks. Other herbs that work well in water are sage, oregano and thyme. When placed in water, they begin to produce roots and will grow new leaves. This is a useful way to prolong the harvest, whether you bring in cuttings from the garden or buy fresh herbs at the grocery store.

The process is easy. Simply cut the ends of each stem and put them in a small jar or cup filled with water. Be sure to remove any lower leaves so they won’t be submerged in the water. Place on a sunny windowsill.

The leaves produced indoors will be thinner and slightly less flavorful than those grown outdoors but will still add welcome flavor to your favorite dishes. Refill the water as needed and enjoy the prolonged harvest for several weeks to come.
